I think that when they refer to induction heating, it is using a coil into which the object to be heated is placed and then a
high current low voltage is applied to the coil and the object in the coil gets hot. Basically a low turn transformer using
magnetic fields to heat, the coils get hot also but not as hot as the object within the coil. Kilowatts of power are needed
but 110v coils can heat small objects. A google on metals useful for induction heating will show a list, seems to
exclude Ti but includes all bicycle frame material and common brazing alloys. Induction stoves work the same way
but with some limitations in metals used in the pots for best results.

Nothing to do with immersion heaters pictured in prior post.
